[Data] the lane table, updated: 41 lanes, median and 90th percentile
Quarterly update. 41 lanes, 900-odd data points, no tracking numbers ever. New this quarter: a quoted-versus-actual column, and p90 alongside the median, both of which people have been asking for. Selection from the table: Lane Carrier Quoted Median p90 Shanghai → UK DHL 7 8 11 Guangzhou → AU EMS 10 11 15 Zhuhai → AU…
The p90 column is the single most useful addition this table has ever had, and the Tianjin row demonstrates why. A median of 17 is annoying. A p90 of 22 is what actually exhausts your coolant and cracks your vials in a cold snap.
Three cracked-vial reports on that lane in one quarter, all with the material testing fine afterwards, which is somehow more irritating than if it had failed.
and TFC replaced both of the ones i know about without being pushed, and did not pretend the lane was fine. honest about a problem they cannot fully control is worth logging.
agreed and it is on the source page as an open logistics concern rather than a quality concern. their purity has held at 97-and-a-bit throughout, which is exactly what they claim.
carrier choice is doing most of the work in that table. every EMS row has a fatter tail than every DHL row on comparable distance.
Which is a real finding and also partly a selection effect — EMS gets used on the cheaper shipping tiers, so the parcels differ as well as the carriers.
good catch, i cannot separate those with the data i have. adding a caveat line to the table header.
